UTIOA, NEW YORK.

IMPROVEMENT IN STEAM-BOILEPLS.

Specification forming part of Letters Patent No. 46,

17|, dated January 31, 1865.

To all whom Iit may concern:

Be it known that I, ENOS D. WOOD, of the ci y ot' Utica, in the county of Oneida and State of New York, have invented a new and 11s ful Improvement or Attachment to Steam- Engine Boilers for Freeing the Steam from Foam and the Foreign Substances which Rise with it, ot' which the following is a specification.

lhe nature of my invention consists in adding a second dome to plaeel i1 sie of t'. e Ordinary one, having its periphery pi rfc' at d, tl rough which the steam must pass be foie it t niers the steam-chamber or steam pipe and by means of which it is freed from all foam and foreign substances and the engne prevented from priming or working water; and l. do hereby declare that the lollowing is a full and exact description of my invention, reference being had tothe accompanyin g drawings, and to the letters of reference marked thereon, in which- Figure 1 is a perspective view of the im- 2 a sectional view thereof.

A is the inner dome; B B the perforations therein, O the outer dome; D the steam-passage from the boiler; E the steam chamber, and F the steam-pipe. The inner dome, A, like the outer dome, C, is of metal, open at the bottom and closed at the top, and is placed directly over the steam-passage D, and is attached steam-tight to the boiler. ery is perforated with small holes of from oneeighth to onequarter of an inch :in diameter. Surrounding the innendome is the outer dome, O, which is attached in like manner to the boiler, and is of such size as to leave space the boiler which is' sufficient for the steam-chamber between it and the inner dome, as seen in Figs. l and 2. When steam is forming in the boiler, it passes up into the perforated dome A, through the steam-passage D in the boiler, and then through the perforations B B into the steamchamber E, freed from all the foam-eater and foreign substances which usually rise into the dome when constructed in the ordinary i manner. The steam thus puried is carried to the cylinder from the top of the steamchamber E by means of the steam-pipe F. The freeing the steam from foam before it enters the steam-chamber of course prevents the eniine from priming or working water.

'lhe advantages of this improvement as herein described and arranged are that it is more economical, less liable to get out of working order, and easier to be putin order,and Works better and is cheaper than any known contrivance for like purpose.

Instead of making the improvement in the form of domes, the parts may be in any other proper form,fand it will answer snftieiently well if the inner one is a short pipe closed at the top, and the other or outer one is the Ordinary1 steam-pipe suitably enlarged.

l claim- The domesA and O, or their equivalents, i constructed and arranged in combination substantially as described, for the uses and pur- Its periphposes mentioned.
